后路椎弓根螺钉内固定结合椎体成形治疗胸腰椎骨折

Treatment of thoracic and lumbar fractures with posterior pedicle screw fixation and vertebroplasty

目的 探讨应用椎弓根螺钉内固定加自固化磷酸钙人工骨（CPC）椎体成形治疗胸腰椎骨折的临床效果。方法 对38例新鲜胸腰椎骨折行椎弓根螺钉系统固定的同时，加CPC行椎体成形。结果 33例获随访5～29个月，无内固定松动及断裂，伤椎高度及脊柱生理弧度无丢失。3例发生CPC渗漏至椎管和椎间孔内，椎管内静脉丛漏2例，椎前静脉漏1例。结论 椎弓根螺钉内固定加CPC椎体成形是治疗新鲜胸腰椎骨折的一种可行方法。

Objective To study the clinical effect of thoracic and lumbar fractures treated by pedicle screw fixation and vertebroplasty with calcium phosphate cement （ CPC ）. Methods 38 cases with fresh thoracic and lumbar fractures were treated with pedicle screw fixation and vertebroplasty with CPC. Results 33 were followed up for 5～29 months. No instrument looseness or breakage was found. No lesioned vertebral height or spinal curve loss occurred. 3 were complicated with epidural and neural foramina leakage of CPC, 2 with vena vertebralis posterior and 1 with vena vertebralis anterior leakage. Condusions It is a feasible way to treat thoracic and lumbar fracture with pedicle screw fixation and CPC vertebroplasty.
